The family of a Manhattan Beach woman who had Alzheimer's disease and went missing near LACMA in 2016 said they were relieved but left riddled with questions after her remains were positively identified.

"There are high-risk individuals that go missing often and they are unable to tell us where they are coming from, where they live, where they need to go, so these are really critical members of the community that utilize Project Lifesaver in trying to get them back from their family members," said deputy Daniel Cerda.

Since it was implemented in 2018, the program has helped locate 31 critically missing people. But before authorities could punch in Dunworth's tracking number, the eight-year-old hero found him a few streets away.

The Dunworth family say they are grateful for his help and for the peace of mind that the program gives them.

"Even though the bracelet didn't do the finding, at least it's in place and we have something to go for," said Roger's wife, Judy.
